Musical Fidelity M6-500i vs Kw - 500


Hello guys
I was browsing around the web today and stumbled across
the latest Super Integrated from Musical Fidelity .
This is a 500wpc into 8ohm beast similar in power to the limited edition Kw -500 , Some changes are evident between these models , The older Kw -500 has an external power supply and MM phono stage and single ended inputs only
along with 6112 milspec valves in the pre -amp section.
The Kw -500 was made in England.
The M6 - 500i has line level inputs only with 1 set of balanced inputs no valves appear to be in this unit making it solid state , The power supply of the M6-500 is onboard . The m6 -500i is made in Taiwan.
Has anyone else compared these two units ? Seems they each have advantages depending on your system setup.
I wonder if the new M6-500i would be much better ?

@fatboyriding - sorry about the delayed response.

I upgraded the power cords to Acrolink 7N-P2040 on the main power supply, and upgraded the umbilical cords to Acrolink 7N-P2030II. The stock cables were only 2 1/2 feet long, so it was difficult to put the main unit any distance away from the power supply. I also upgraded the umbilical from the power supply to the preamp section with a 7 pin Revelation Audio Labs cord. Finally, I upgraded the fuses in the power supply to HiFi Tuning. All made nice improvements. I think there are some interconnect(ions) inside the main unit-that if I remember are just the standard shielded factory variety.  May have another mod opportunity there. :)

I've got a KW 500 that i picked up used a couple years back. I'm wondering how drastic was the improvement going with the revelation audio umbilical and Acrolink cords?

Where can I find info on the Acrolink umbilical cords? A web search does not bring them.

Thanks,

BTW, Pro-Ject has purchased Musical Fidelity. I think it happened in May, 2018. Also I had heard the Musical Fidelity M6-500i at a dealers place driving Vandersteen 2CE speakers. Tremendous amp, finess and power.

@shahram -  Sorry I didn't see your original question.

I ordered the Acrolink over ebay from a Japanese seller, and bought some (4) fairly generic Neutrik 3-pin connectors.
